The Institute of Plant Protection, National Research Institute (, is a public research and development organization under the Ministry of Agriculture and Rural Development. It is an important scientific, research, implementation and popularization centre, also offering consultancy and advisory services in the area of plant protection, including quarantine issues.


The Regional Experimental Station in Rzeszów is a field research organization directly supervised by the Institute of Plant Protection – NRI in Poznań, and operates in the south-eastern part of Poland. The station is located in close proximity to the borders with Slovakia and Ukraine.

Selected events from the Station’s history:

The Regional Experimental Station in Rzeszów, Institute of Plant Protection – NRI (TSD IOR–PIB), began its operation on 2 May 1971. The directors of the Institute appointed Zdzisław Przybylski, PhD (later Professor) to organize the Station in south-eastern Poland, and he became the first head of the Station and held this position until the end of 1999.

The immediate incentive for the establishment of the Station in Rzeszów was aid from the Food and Agriculture Organization (FAO), United Nations Development Programme (UNDP), and the implementation of the Resolution of the Council of Ministers No. 64/70 of 18 May 1970 on the organization of research in the field of toxicology and safe use of pesticides and control of their residues in food and the environment. The main task of the Station’s organizer was to create a Laboratory for Pesticide Residue Analysis in crops, according to the regulation of the above-mentioned Resolution by the Council of Ministers. This task has been fully realized after the allocation of two rooms with 36m2 surface area in the Provincial Laboratory of Quarantine and Plant Protection Station in Rzeszow, in Różana street.

Initially, the activities of the Station were oriented at the analysis of pesticide residues, but in a short time the scope of work was expanded to include biological research in addition to scientific and research projects carried out by the Institute. As a result, the Field Experimental Laboratory was established, and it began testing the efficiency of new plant protection products.

Activities of the Pesticide Residue Analyses Laboratory:

In the 1990s the Institute of Plant Protection, through cooperation with Poland and Hungary Assistance for Reconstructing Their Economies (PHARE), received specialist analytical equipment for testing residues of plant protection products in soil, water and plant material. Modern equipment enabled the extension of the scope of research and improvement of the quality of results. Apart from research activities the Laboratory began providing services to individual clients, mainly processors and exporters of fruit and vegetables. In addition to the routine analysis of plant material, water and soil, the staff of the laboratory improved and developed new research methods, which were successfully implemented in their everyday work.

Under the project co-financed by the European Union from the European Regional Development Fund for 2006-2007, the laboratory gained modern equipment, including a liquid chromatograph (Waters 2695) and a gel chromatograph (Waters 2487).

In 2008 the Institute of Plant Protection was granted the status of a National Research Institute, and the laboratory’s name changed to the Pesticide Residue Analyses Laboratory (LBPŚOR).

An important step in the operation of the laboratory was made on 8 September 2011, when it received an Accreditation Certificate for a Research Laboratory, No. AB 1279, from the Polish Accreditation Centre (PCA – The laboratory has implemented a Management System according to the PN-EN ISO/ICE 17025:2005 standard regarding “General requirements for the competence of testing and calibration laboratories”.

The competence of the Laboratory is regularly inspected and confirmed through participation in laboratory proficiency tests, e.g.:

  • European Commission Proficiency Test on Pesticide Residues in Fruit and Vegetables (EUPT), University of Almeria, Spain,
  • European Commission Proficiency Test on Pesticide Residues in Cereals (EUPT/SRM), National Food Institute, Technical University of Denmark,
  • Food Analysis Performance Assessment Scheme (FAPAS), Central Scien­ce Laboratory, Norfolk, UK.

The Pesticide Residue Analyses Laboratory carries out activities in the monitoring of pesticide residues in agricultural crops (mainly fruit and vegetables), fodders, and in the environment (mainly soil and water). It performs analyses of over ten thousand various samples, including testing and reporting the presence of biologically active substances in water intakes for municipal waterworks, in deep wells, sewage and soil contaminated with plant protection products.

The main task of the laboratory, carried out from the early days of the Station, is the official inspection of pesticide residues in vegetables, soil, water and feed components.

Operations of the Division of Field Experiments:

The operation of the Division of Field Experiments dates back to the establishment of the Station. From the very beginning it dealt with scientific and research problems important for many agricultural disciplines.

During its over 40-year-long operation, a number of studies have been carried out at the Station, and they have concerned, e.g.:

  • the monitoring of the occurrence and harmfulness of various pests in crops of wheat, barley, oats, maize (fodder and sweet), sorghum, field beans, peas, potatoes, beet, rape and others,
  • development of programmes for the control of pests in organic, integrated and conventional farms,
  • the biology and ecology of selected species of pests (e.g. cereal leaf beetles, aphids, thrips, pea weevil, gout fly, gall midges, Colorado potato beetle, Western corn rootworm, European corn borer, owlet moth, pea moth and others).
  • aetiology of selected diseases, e.g. in cereals, maize, potato, rape (e.g. including potato blight, Septoria tritici blotch in wheat, infection of maize cobs by Fusaria spp., infection of wheat by dwarf bunt Tilletia controversa, leaf rust, seedling blight, common smut and head smut in maize, Alternaria diseases in Brassicaceae, black leg in Brassicaceae, and many others), and the occurrence, harmfulness and control of selected diseases in button mushrooms,
  • monitoring of useful entomofauna in agricultural crops ­and vegetables,
  • aetiology, occurrence and harmfulness of viruses, bacteria and fungi responsible for plant diseases,
  • the susceptibility of transgenic maize varieties from the MON 810 line and conventional varieties to infection, accumulation of mycotoxins and damage caused by Ostrinia nubilalis,
  • effects of transgenic maize with Cry1Ab protein expression on non-target organisms,
  • resistance and susceptibility of selected varieties of cereals, maize, peas, field peas and potato to infestation and damage by pathogens and pests,
  • effects of disease and pest control on the level of mycotoxins in cereal and corn grain,
  • suitability of various trap models for the monitoring and signalling of control of the European corn borer, owlet moth, Western corn rootworm and others,
  • registration of the occurrence of individual crop pests in cereals, maize and potato for the purpose or regional signalling of dates for plant protection treatments.

Directly after the establishment of the Regional Experimental Station in Rzeszów, research was mainly focused on entomology and herbology, and phytopathology was a minor area of interest. In 2000 a phytopathology laboratory with professional research equipment was established.

The operation of the Division of Field Experiments has been strongly focused on entomology, particularly studies on methods for the protection of crops against pests. A very important date for Poland was 22 August 2005, when the staff of the Station detected, near Rzeszów, for the first time in Poland, the Western corn rootworm (Diabrotica virgifera Le Conte) – the most dangerous maize pest in the world (and a quarantine pest in the European Union until 2014).
